ABSTRACT.- The conditions of wing reduction (brachyptery) and loss of wings (aptery), and modifications thereof, are reviewed across all known
families of Lepidoptera where this has been observed in either males or females, or both sexes. Brachyptery or aptery is known in 35 families of
Lepidoptera, including families or species where a kind of brachyptery is only evident as extreme wing reduction of the hind wings. Examples from
most families known to have brachyptery of some form are illustrated among 147 figures.

Brachyptery (wing reduction) or aptery (loss of wings) is an
unusual phenomenon in adults among several orders of insects
(La Greca, 1954). In Lepidoptera, brachyptery has been reviewed
most recently by Hackman (1966), Dierl and Reichhoff (1977),
and by Huemer and Saltier (1989). Earlier comprehensive papers
on brachyptery in Lepidoptera were by Chapman (1913, 1913a,
1917), Hudson (1912), Jordan (1884), Knatz (1891), and Porritt
(1913). Lepidoptera with some degree of wing reduction or
complete loss of wings in one or both sexes have been recorded
now in 35 families (see Table 1):
Hepialidae, Tineidae, Eriocottidae, Psychidae, Oecophoridae,
Lecithoceridae, Elachistidae, Gelechiidae, Blastobasidae,
Cosmopterigidae, Scythrididae, Carposinidae, Glyphipterigidae,
Yponomeutidae, Thyrididae, Pyralidae, Heterogynidae,
Zygaenidae, Himantopteridae, Somabrachyidae, Cossidae,
Limacodidae, Tortricidae, Papilionidae, Lycaenidae, Epiplemidae,
Geometridae, Anthelidae, Lasiocampidae, Sphingidae,
Notodontidae, Thyretidae, Lymantriidae, Arctiidae, and
Noctuidae.
Among most of these families, brachyptery is very rare (e.g.,
Hepialidae, Pyralidae, Tortricidae, and Noctuidae), but in a few
families, notably Psychidae, Heterogynidae, Somabrachyidae, and
Lymantriidae, it is very common for most species to have
brachypterous females, many being apterous (Bourgogne, 1958;
Buszko and Sliwinski, 1980; Daniel and Dierl, 1966; Powell,
1911; Zilli and Racheli, 1989). In some cases, complete brachyptery
is not evident, but the hindwings have extreme reduction in
size (e.g., some species of Lecithoceridae, Cosmopterigidae,
Himantopteridae, Cossidae, Limacodidae, Geometridae, Sphingidae,
Notodontidae, Thyretidae and the arctiid subfamilies
Ctenuchinae and Syntominae). Not included in this definition of

brachyptery are species having extremely narrow wings (stenopterous)
as in many microlepidoptera, particularly in such families
as Gracillariidae, Lyonetiidae, Cosmopterigidae, and Sesiidae, or
such wing modifications as in Alucitidae, Oxychirotidae, and
most Pterophoridae. Other families excluded from the definition
of brachyptery include such families as Brachodidae, where the
enlarged abdomens of the mostly sessile females (Heppner, 1983)
of some European species give the appearance of a kind of wing
reduction, yet where the ratio of female wings to male wings is
not very much different from 1:1.

Table 1 lists the known brachypterous and apterous species
from a search of the literature and museum collections, yet some
species may have been missed and many more will undoubtedly
be added as additional searches are made of alpine and xeric
(eremic) regions where such species are most apt to be found.
There also are other species known to be brachypterous from
such places as the high elevations of the Rocky Mountains of
North America, but which are not yet described (Hodges, in. litt.).
Butterfly species, other than four Papilionidae and one Lycaenidae
with relatively extreme hindwing reduction, or any of the
most primitive moth families (four species of Hepialidae being
the only known exceptions), do not exhibit any brachyptery, as
opposed to mutations (Fig. 141-144) or rare eclosion accidents
(Bowden, 1963; Shapiro, 1983). Hindwing reduction included in
Table 1 refers only to an extreme form, with a fore- to hindwing
ratio of near 3:1 or more (a few cases are included where there
is hindwing reduction on the borderline of these criteria, notably
in Zygaenidae, Papilionidae, Lycaenidae, and Sphingidae).
Hindwing reduction is common among Syntominae and the
Ctenuchinae (Arctiidae), for example. One of the most extreme
cases is a Brazilian species, Diptilon culex Draudt, where the
reduced hind wings are so small that they are hidden among the
thoracic scales at the wing bases (Draudt, 1915); other Diptilon
species (Fig. 123-126) also show some hindwing reduction. In
Tineidae there is at least one extreme example, the species
Meessia brachyptera Passarin d'Entreves, where the forewings of
the female are only slightly reduced but the hindwings are minute
(Fig. 2). Other families with examples can be noted in Table 1.
The development of wing reduction only in the hindwings is
curious and appears without apparent reason in Lepidoptera other
than possibly being sexually derived, since among several groups
the females have more developed hindwings and only the males
have markedly reduced hindwings. Cases of reduced forewings
are known in some families (e.g., Dismorphiinae in Pieridae), but
this really is narrowing of the forewings, or enlargement of the
hindwings, and not a kind of brachyptery as considered here.
Brachyptery usually occurs only in the female but it has been
recorded in both sexes in a few cases, primarily in moths from
isolated oceanic islands: the Kerguelen Is. (Viette, 1948) and
Heard Id. (Common, 1970) of the south Indian Ocean; the
Antipodes Is. (Salmon and Bradley, 1956), Auckland Islands
(Dugdale, 1971), and Campbell Id. (Dugdale, 1964; Viette, 1954)
near New Zealand; and the Falkland Is. (Bradley, 1965) of the
south Atlantic Ocean. Families from these island faunas of
brachypterous moths include Tineidae, Oecophoridae, Elachistidae,
Yponomeutidae, Tortricidae, and Pyralidae. The only known
species with brachypterous wings in both sexes from a continental
area, although from coastal sand dunes, is a species of Scythrididae,
Areniscythris brachypteris Powell (Fig. 26), from California
(Powell, 1976). Another undescribed sand dune scythrid appears
to reside in coastal dunes of western Florida. Both scythrid
species are unusual in the construction of larval sand tubes of silk
at the base of their host plant. Hackman (1966) referred to a
Gelechiidae species from Morocco, Ephysteris curtipennis
(Zerny), as another continental species where both sexes are
brachypterous, but although the male does have extremely
narrowed wings (stenopterous), Povolny (1968) noted that the
males of this species can fly.
Brachyptery on both fore- and hindwings, or even complete
wing loss, is most common in females. This condition is normal
in the families of Lymantriidae, Somabrachyidae, and Psychidae.
Likewise, it is a regular occurrence among many primitive
Tineoidea. Typically, the females are relatively immobile in
these groups, often sequestered within the larval and pupal case,
as in the example of the Psychidae or bagworms. All are
terrestrial except for one case of brachyptery among the few
known aquatic moths in the family Pyralidae: Acentria ephemerella
(Denis and Schiffermiiller) [formerly Acentropus nivea
(Olivier)] (Fig. 43). In the case of this aquatic moth, the female
is dimorphic, with some females of a population fully winged and
others almost apterous (Berg, 1941).
Female wing reduction in Lepidoptera is rarely polymorphic.
The dimorphic example of the aquatic moth, Acentria ephemerella
(Pyralidae), has already been noted. Another form of
facultative wing reduction occurs in a few species having seasonal
forms, one generation having fully winged females and another
generation having brachypterous or apterous females; this wing
reduction is usual among some species with autumn or winter
generations in temperate climates (Kimura and Masaki, 1977;
Sachrov, 1914). Wing reduction polyphenism of this kind is
prevalent in some Lymantriidae, e.g., Orgyia thyellina Butler
(Cretschmar, 1928). In Thaumetopoea species (Notodontidae)
females usually are winged but can be brachypterous on occasion
(Loritz, 1952). Wing reduction in geographical variation is rare:
an example is the arctic geometrid Psychophora sabinii Curtis,
where the females have some wing reduction on the Pribilof Is.,
Alaska, but elsewhere are fully winged (Downes, 1964, 1965).
The same occurs with the arctic arctiid, Pararctia subnebulosa
(Dyar) (Sotavalta, 1965). Another case of geographic brachyptery
occurs in the geometrid Lycia hirtaria (Clerck), females beine

of brachyptery among island dwellers and coastal areas, however,
may have developed wing reduction due to other environmental
parameters, notably thermoregulation or wind adaptation (Powell,
1976). Brachyptery among the aquatic Pyralidae undoubtedly is
due to some adaptive advantage under water, possibly easier
movement for oviposition, although there may be some offsetting
factor in the reduction in underwater air retention beneath normal
folded wings as is prevalent in some other Nymphulinae pyralids
which also dive underwater to oviposit (Berg, 1941).
In Lepidoptera, part of the probable evolutionary development
of wing reduction in females involves two modes of brachypterous
females (Hackman, 1966): 1) the case where females have
developed enlarged abdomens with many eggs prior to oviposition,
making flight difficult; and 2) the case where females have
a normal abdominal size and are mobile, thus capable of rapid
flight when desired. The Psychidae females and some Lymantriidae
are examples of the former type and such moths as the
scythrid, Areniscythris, are typical of the latter type. A development
towards brachyptery may be evident in species like the
European arctiid Artimelia hemigena (Grasl.) (Fig. 109-110) or
the noctuid Agrotis fatidica (Hiibner) (Fig. 132-133): these
species are listed in Table 1 as brachypterous, but the females
have only somewhat reduced wings. Given this range of
brachypterous females, considerable speculation has been made
as to the development of brachyptery in Lepidoptera. Theories
have been proposed by Naumann (1937), Eggers (1939), and
Downes (1964). Their main points pertain to a development of
brachyptery in response to decreased mobility due to abdominal
enlargement from excessive egg numbers, with adaptive mutations
progressing to brachypterous or apterous forms. A number of
species worldwide exhibit enlarged abdomens in the female,
resulting in reduced flight or little apparent flight: e.g., females
of the Great Basin tortricid, Synnoma lynosyrana Walsingham,
have an enlarged abdomen prior to egg laying and do not readily
fly (Powell, pers. comm.). Among Brachodidae, the Palearctic
genus Brachodes has females that are relatively sedentary prior
to copulation and only fly for egg laying (Heppner, 1983;
Heppner and Duckworth, 1981).
As noted previously, in various habitats (cold regions, high
altitudes, eremic regions, and coastal areas) there appear to be
adaptive benefits to brachyptery. Hackman (1966) notes,
however, that the evolution of extreme wing reduction in some of
the almost larviform females of Lymantriidae (Fig. 102-108) and
Psychidae (Fig. 18-22) is not easily explained. The more mobile
type of brachypterous female is also not explained by the
Naumann-Eggers-Downes theory, as Hackman (1966) calls it,

since three types of these mobile forms are evident: 1) arboricolous
cold-season species; 2) terricolous species; and 3) aquatic
species (in this last case, only Acentria ephemerella is known).
Additional theories of the evolution of brachyptery in these forms
involve environmental adaptations (e.g., thermoregulation,
protection from high wind, cold stupor, etc.), whereby sedentary
females remain on or near host plants (Chapman, 1913; Hudson,
1912; Wood, 1913). Additionally, there is predator evasion as a
probable adaptive advantage for many brachypterous species (e.g.,
Sattleria dzieduszycskii (Nowicki)) which hide in low alpine
plants (Hackman, 1966). Wing reduction in the aquatic species
is likewise not easily explained by the above theories, although
environmental adaptation for oviposition would seem to be the
cause, but this unique case is more complex due to the dimorphic
female, which may be fully winged or brachypterous within the
same population and generation.
Species listed in Table 1 are brachypterous to fully apterous
(usually only females) in one or both sexes (M or F), or have an
extreme degree of hindwing reduction (*). Examples listed
having only hindwing reduction usually are included only if this
condition is extreme (fore- to hindwing ratio of 3:1 or more) but
a few borderline cases are included where some hindwing
reduction is evident (especially, Zygaenidae, Papilionidae,
Lycaenidae, and Sphingidae). The range of each taxon is noted
to the far right of each name. A few species are facultatively
brachypterous, where only some individuals develop this condition,
and this is noted after the name; facultative here also
includes cases where a species has brachyptery only in parts of
its range (e.g., Psychophora sabinii, in Geometridae). Names
listed in Table 1 are considered valid herein, but various researchers
may list some of them as synonyms (e.g., Phigalia in
Geometridae is used as a valid genus for Nearctic species, yet it
is listed as a synonym of Apocheima by many European workers).
Faunal literature has been searched for all known references to
brachypterous Lepidoptera (Bradley, 1958, 1965; Burmann, 1951,
1954, 1956, 1957, 1958, 1973, 1977; Chapman, 1913a; Chauvin

(* = extreme hindwing reduction only: F = female; M = male)
1. Pseudoschoenobius opalescalis: brachypterous females in winter on Mojave
Desert sand dunes, California (Powell, pers. comm.).
2. Zygaenidae are on the borderline of the criteria of hindwing reduction used for
including taxa in this listing; likewise for Papilionidae and Lycaenidae.
3. Sphingidae listed have fore- and hindwing ratios of only somewhat better than
a 2:1 ratio, thus are on the borderlin of the criteria for listing herein.
4. Noctuidae: Eriopygodes imbecilla has only slight brachyptery in the female.
